Grinding mill classification

According to the different characteristics of the grinding mill, milling machine can be divided into Raymond Mill, ultrafine grinder, Ball Mill, ground mill, etc., different milling machine has a different characteristics of the crushing

Structure of Raymond Mill

  • 1, three-dimensional structure, small footprint, complete sets of strong, from the block material to the finished product independent of a production system.
  • 2, finished fineness uniformity, through the screen rate of 99%, which is difficult to have other milling equipment.
  • 3, the machine drive with a closed gear box and pulley, smooth transmission, reliable operation.
  • 4, the important components are used high-quality steel, wear parts are used high-performance wear-resistant materials, machine wear high performance.
  • 5, the electrical system using centralized control, milling workshop can be achieved basically no homework, and easy maintenance.

What are the fields for ball mill applications?

The structure, performance and other advantages of the ball mill are more prominent, so it has a wide range of application value, can deal with iron ore, gold ore, molybdenum ore, aluminum, limestone, quartz, diabase, dolomite, calcite, All kinds of materials, get gravel plants, concentrators and other customers of all ages, for building materials, construction, roads, railways, chemicals, water and other industrial sectors to provide more high-quality materials to promote the development of various fields and progress.

Ball mill highlights the advantages of performance

  • 1, high yield, good material: bar grinding media, grinding of materials, from the surface contact with the line contact, the material is more uniform, and the higher yield;
  • 2, power savings: compared to the old bar mill to save power about 50%, in a reasonable motor configuration, the kinetic energy to give more adequate energy consumption more savings;
  • 3, environmental protection production: the structure of a unique design to reduce the dust fly out to avoid tailings, sewage and other polluting the environment, the overall realization of environmentally friendly production;
  • 4, long life: vulnerable, the core components are the use of high-quality materials design, and after ingenuity design, improve the quality of equipment to extend the life of more than 3 times;

Vertical mill performance characteristics

LM series vertical mill grinding process is the realization of the motor drive disc and roller grinding of the material crushing, the motor through the reducer drive disc rotation, the material by the lock the wind feeder from the feed port in the center of the disc, while hot air from The air inlet enters the mill. When the disc is rotated, the material is crushed by the roller of the roller under the action of centrifugal force. The crushed material is brought by the high speed airflow at the edge of the grinding wheel, and the incomplete material is broken back to the grinding wheel for re-grinding. The coarse powder from the cone to the disc to re-grinding, qualified fine powder with the air together with the mill, collected through the dust collection device. The moisture-containing material is dried during the contact with the hot air, and the moisture content of the product can be met by adjusting the hot air temperature to meet the requirements of the different humidity materials. Product thickness adjustment can be done through the separator, fully meet the user's production standards for materials.


  • 1, easy to operate, clean and environmentally friendly
  • LM series vertical mill installation automatic control system, can achieve remote control, easy to operate. Through the maintenance of the cylinder, flip arm, replace the roller sleeve, liner convenient and quick, can reduce the loss of downtime. LM series vertical mill equipment as a whole sealed, the system under negative pressure, no dust spill, will not pollute the environment.

  • 2, high performance, low noise
  • Hot air in the mill directly with the material contact, drying ability, energy conservation. By adjusting the hot air temperature, can meet the requirements of different humidity materials. Material in the mill to stay a short time, easy to detect and control the product size and chemical composition, reduce the repeated milling, product quality is more stable. The roller sleeve and the disc liner are provided with means to prevent direct contact to avoid destructive shocks and severe vibrations. LM series vertical mill structure is reasonable, so the vibration is small, low noise.

  • 3, covers an area of ​​small, wearable
  • LM series vertical mill set broken, dry, grinding, graded transport in one, compact layout, covers an area of ​​only 50% of the ball mill system. Roller in the disc directly crushed grinding materials, energy consumption than the ball mill system by 30% -40%. Roller and liner using high-quality materials, reduce wear and prolong the

T130X to strengthen the advantages of ultra-fine grinding products


  • 1, high precision and high strength. In the body and the base of the soft connection, to avoid the grinding chamber vibration on the body and the impact of the machine to improve the accuracy of the analysis. With high strength, anti-cracked ductile iron production of the base, a good impact resistance.
  • 2, collecting powder efficiency. Bypass collector with the same resistance program to avoid the two sets of powder output is different, and the collector two discharge and dust collector outlet in the same line, easy to collect fine particles, effectiveness.
  • 3, high yield and low energy consumption. The analyzer uses high-density blades, the airflow resistance decreases, the fineness and the yield increase. Frequency control machine, more accurate control, more energy efficient, high degree of automation.
  • 4, stable and reliable. Make full use of domestic imitation Germany Flanders reducer advantages, improve the stability of the equipment. Host and reducer with flexible sleeve pin coupling, improve the reliability of the equipment. Reducer and motor with V-belt transmission power, which is conducive to overload protection, more secure.
